    Summary: pgx SQL Injection via Protocol Message Size Overflow

    Details: ### Impact SQL injection can occur if an attacker can cause a single query or bind message to exceed 4 GB in size. An integer overflow in the calculated message size can cause the one large message to be sent as multiple messages under the attacker's control. ### Patches The problem is resolved in v4.18.2 and v5.5.4. ### Workarounds Reject user input large enough to cause a single query or bind message to exceed 4 GB in size.
